[Gender-swap + male-to-female transformation + no romance + city life + daily life] A super-brainy academic named Niu Qiang, the fun-loving Yang Jian, and the artsy Lin Sheng were once rivals. After unexpectedly becoming women, the three become sisters.
Niu Qiang has worked relentlessly at her studies since childhood, determined not to disappoint her family. But the more she loses herself in the ivory tower, the more her promising future slips away, until she ends up as a university teacher in a small city in southwest China, with a meager salary and enormous academic pressure.
Born and raised in Beijing to a well-off family, Yang Jian happens to enroll at the university where Niu Qiang teaches. An outgoing cross-dresser who loves to dress up in colorful, glamorous outfits, Yang Jian baffles Niu Qiang but also brings her plenty of joy.
Lin Sheng is a small-town test-taking ace who refuses to settle for an ordinary life. After graduating with a bachelor's degree, Lin Sheng gives up on further study, but the blows of reality eventually leave them lost in an endless haze.
The three unexpectedly find themselves trying to make a living in Beijing. Whether due to their personalities or the pressures of life, they unexpectedly start dressing as women and embark on a new life as women.
Their gender transformation lets them escape the atmosphere of competition, blame, and attacks between men. They dress as women together and live the way women do, respecting and relying on one another as they become sisters.
Along the way, they meet many women at the bottom of society who are struggling through hardship. Together, they offer one another warmth and support, and their world grows ever larger.
